Prepare! — Start! — Release! — Repeat! — Switch! • ”I tried quite a few and this is the best one hands down!" • ”I might actually DO the exercises my PT prescribed, thanks to this app!" • ”I've looked at many timers for stretches, floor exercises, weight lifting... and this is the perfect one!" TIMER AND COUNTER FOR PHYSICAL THERAPY Keeps time, counts reps and sets, and lets you focus on your exercise, or something else—not the clock. YOU ENTER YOUR OWN EXERCISES Add instructions and photos, or a weblink, and set up your entire routine, exactly as prescribed by your therapist. Fine-tune cues and timers to match your personal pace. Note: this app does NOT offer pre-defined exercises (other than a few examples). KEY BENEFITS *** Some features are available only during the free trial or with a paid subscription as described below. • Stop counting seconds and reps—focus on proper form, breathing, or even reading or listening to music. • Clear voice and tone cues that work alongside music, podcasts, or when the app runs in the background. • Store all exercise instructions: notes, photos, and web links, with spoken guidance in a voice you choose. • Precisely adjust timers to fit your needs. • Schedule exercises and receive reminders. • Take notes after each exercise and email reports directly to your physical therapist. • Export workouts to PDF, including instructions, photos, and schedules. • Apple Health integration records exercise type and duration. MORE FROM THE REVIEWS • "The app is very easy to use and has resulted in the quality of my exercises increasing markedly … it does meet my needs to a "T"!" • "Best one ever. Have tried 2 others. At 65 stretching is important and this app helps." • "…it lets you focus on other things if you have simple boring exercises." BASIC VERSUS PAID SUBSCRIPTION CAPABILITIES Without a subscription, PT Timer provides limited basic functionality.

You must enter exercises tailored to your own needs. TERMS OF SUBSCRIPTIONS Several subscription options are available with different renewal periods.

Features
Read full description

Seconds is an interval timer for HIIT, Tabata, EMOM, circuits and any workout built from timed intervals. It calls each interval out loud, keeps running with the screen off, and runs on iPhone, iPad and Apple Watch. Apple has featured it, and Joe Wicks, The Body Coach, has said it is the fitness app he uses more than any other. BUILD ANY WORKOUT - Start from a HIIT, Tabata or circuit template, or build a timer from scratch with sets, rounds and intervals of different lengths. - Chain timers into one compound timer, so a warm-up flows into the main set and then a cool-down. - Color-code every interval so you know what is coming before the beep. - Share a timer with a friend in one tap. HEAR IT, DON'T WATCH IT - Voice cues call out each interval by name and warn you before the next one starts. - Beeps and bells are there too if you would rather not be talked at. - Play your own music, per timer or per interval. Cues duck the music and it comes back up when they are done. - The timer keeps going in the background while you use other apps or the screen sleeps. ON THE GYM FLOOR - A full-screen, color-coded display you can read from across the room, in portrait or landscape. On iPad it uses the whole screen. - A lock button stops a stray tap from pausing your set. APPLE WATCH - Seconds runs on the watch by itself, so the phone can stay in the locker. Timers you build on the phone sync to the wrist, and Quick Intervals builds a basic circuit on the watch itself. MORE TIMERS - A stopwatch that marks your best and worst laps. - A countdown timer with five preset durations (three on Apple Watch). APPLE HEALTH - Save workouts and mindful sessions to Health. With a heart rate monitor connected, Seconds reads your body measurements and year of birth from Health to estimate calories burned. FREE TO TRY, ONE PAYMENT TO UNLOCK - Everything is available from the first launch. Build any timer and run it. - Each timer locks after you run it once. A single in-app purchase removes the lock on every timer you make. SECONDS AND SECONDS PRO - Seconds Pro is the same app, paid once up front, with nothing to unlock. The two are separate products and a purchase in one does not carry over to the other. If you bought Seconds Pro, download Seconds Pro. If you bought the unlock in Seconds, download Seconds and use Restore Purchases.

ReceptionRating · Positive reviews · Number of ratings

Seconds Interval Timer holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Seconds Interval Timer has 24K ratings behind it against 95, so its average is the more settled of the two. Written reviews complicate that: 81% of PT Timer's written reviews are positive against 75% of Seconds Interval Timer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

PT Timer ships an update every 5 weeks, Seconds Interval Timer monthly. The most recent releases landed on August 11, 2026 and September 25, 2026 respectively.
